' IMPROVED DEVICE FOR. SPLITTING- MATCH-SPLIHTS.

Ihe Sshedule referred to in these Letters Patent and making part oi thesame.

To all whom it may concern:

Be it known that we, M. D. MURPHY and OHIO O. BARBER, of Middlebury, inthe county of Summit, and

State of Ohio, have invented a new and improved Match-Splint Gutter; andwe do hereby declare that the following is a full, clear, and exactdescription of the construction and operation .of the same, referencebeing had to the accompanying drawings, making a part of thisspecification, in which Figure l is a cross-section through line as a:of fig. 2.

Figure'2is an edge view of the instrument when made with the cuttersarranged side to side.

a Figure 3 is a similar view, showing the cutters arranged corner tocorner, and the edges bevelled difi'erently from the instrument abovereferred to.

Figure 4 is a side view of the instrument represented in fig. 3. V

Figure 5 is a cross-section through the line :1 y of figs: 3 and 4.

"The object of this invention is to produce a cutter which can be keptsharp more easily-and perfectly than those hitherto used, and which willeconomize the material to better advantage. To this end,

' Theinvention consists, first, in theform of the edge,

and of the holes through which the splints are forced,

and secondly, in the method of forming the said edge and holes inmanufacturing the instrument.

The instrument is formed of a single piece of metal, having its endsextending beyond the cutting-edge,"so

that they can be secured and held firmly by the ma chine in which it isoperated.

In the drawings these ends are represented at a a, and the cutting-edgeis shown at A A The holes 6 6, through which the splintsare forced, arenot made round, as heretofore,'but square, and are arranged as shown infigs. 2 and 3, or in any other suitable manner.

The cutting-edge of the instrument may-come out flush with the ends a a,or may be left slightly retreat ing, as shown at the shoulder 12, fig. 4r From a line, 0, near the middle of its side, the instrument isbevelled towards the edge, and on the opposite side it is also slightlybevelled, so that the cutting-edges, between the holes 0 e, terminate incomparatively sharp points, which strike the wood in advance of theother parts of the edge, and penetrate it easily. A

When the holes are arranged side to side, both sides of the instrumentare flat and straight, and the thin cutting-edge .may be slightly raisedabove the rest of l the instrument, as seen at A, figs. 1 and 2.

When the holes are arranged corner to corner, the metal is cut awaybetween thein on the bevelled'edge, as shown at i i and onthe oppositeor thin edge, as seen at m m, figs. 3 and 4. around the holes e e isthen sharpened down to a fine edge, if preferred, or it may be left, asseen in fig. 2, sharpened only by the bevels of the sides, abovedescribed.

When made in this form, every part of the edge can be made and keptsharp without diificulty, so that the splints can be out better, andwith the outlay of less power than heretofore, while, from the form andarrangement ofthe holes, a great saving of the wood is effected. I

The cutters are formed by preparing the metal in theshape abovedescribed, and. drilling a small round hole where the centre of eachsquare hole is ultimately to be, and then, having removed the drill,forcing thrbugh each round hole a square punch a little larger that 'thehole; then another, a little larger than the former, and so on, till thehole is of the required size.

Having thus described our invention,

What we claim as new, and desire to secure by Let- 'ters Patent, is-

The instrument represented in figs. 2 and 3, as and for the purposedescribed and shown.
